Attack is one of the combat actions a creature can take on its turn. It is a direct attack against a single enemy (although abilities may alter that). The damage inflicted is increased by the attacker's Attack stat, and reduced by the target's Defense stat.

Many abilities in Siralim are triggered when a creature attacks, is attacked, or is killed by an attack, so it is important to understand what is an attack and what is not. For instance, Penant Reprisal will not be triggered when a creature is damaged by a spell or by Splash, Cleave, or Thrust.

An attack has a chance to be a mortal blow, which deals significantly more damage than usual, or a glancing blow, dealing significantly reduced damage.
